Method of detecting stolen vehicles from presence of signal suppressors

SUBSTANCE: control points are placed on motorways and are provided with receivers for detecting a source of interference for GPS and GSM signals. Photographic and video capturing of vehicles on the motorway is performed upon detecting interference and the data are transmitted to a remote server. Data received at the server from multiple control points are processed to detect licence plate matches. Data on said licence plates and direction of movement are transmitted to road patrol service posts nearest to the last point where the interference was detected.

EFFECT: high efficiency of detecting stolen vehicles.

The invention relates to the field of automotive burglar alarm and can be used to locate stolen vehicles in the process of their movement on the freeway.

Today there is an acute problem of finding stolen cars. Known means of protection against theft of the vehicle, such as bugs "Autovon" [1] to track the vehicle's position on the satellite navigation system GPS, the position of the radiating station operator GSM. The thiefs are aware of the presence of such "bugs" and when theft take measures for their suppression. Why use a system of "jamming" as cellular communication [2], and against the GPS signals [3]. Already use, and will probably use the "jamming" on other tools, such as 3G/UMTS 2100 MHz, SOMA 450 MHz, 4G/LTE800 MHz, 4G/LTE2500 MHz. At the time of car theft, hijackers include "jamming" and do not turn them until you bring the car in so-called "settler" or special underground garage, blocking the signals of the GSM and GPS. Therefore, the system of [1] are ineffective. In addition to using systems [1] it is advisable to search hijacker on by "jamming", i.e., to determine the position of "jamming" and therefore a potential hijacker.

The closest solution is the technology that description is cited in [3].
It consists in the following.

Suppressors are a serious threat to the future of intelligent transport systems. Their use is prohibited by law, and illegal use may be prosecuted. To know the exact number of working suppressors, you need to place the detectors suppressors on special points and to record interference. Good locations such detectors for the initial measurements can serve as a main junction.

Test the interference detection was carried out recording using five static receivers, located in the Central part of the lab GATE.

Detection of interference source based on the monitoring signal-to-noise suppressor (JNR). To prosecute intruders interfering, you must install the suppressor is a hindrance. So the signal was analyzed in the time-frequency interval of the characteristic chirp signal canceller. The gain in the input stage was set at the minimum value for the input cascade could cover high power interference.

The chirp pulse hijackers create in the range from 9.4 to 44.9 MHz band E1/L1 frequency (other bands were not considered). Others generate harmonic oscillations 3 dB bandwidth of about 0,92 MHz and who have termozulia resonant frequency around the resonance frequency Galileo/GPS.

First recorded signals using the chirp-suppressor located in the Central point. The suppressor is outside of the vehicle in line of sight. Measurements in this position at a distance of 200 meters from the suppressor on short-term Fourier transform of the signal clearly shows the presence of the chirp signal.

During the second measurement, the suppressor was placed in the car. The car went from a position where it was activated suppressor, and drove along the main street past the detector. Then the car turned around and went the same way. Filmed indicators JNR.

Measurements of the degradation values of C/N0 for GPS PRN9 Figure 22 and GATE PRN 46 show that the suppressor can be detected and identified in the area of distributed network receiver.

The next step in the development of a comprehensive monitoring network interference is the presence of automotive GNSS receivers that can detect and report the presence of noise. For this scenario was activated suppressor in one moving vehicle and another vehicle moving in the same way, measurements were performed using receiver ipexSR.

Both cars went from one position. It was first included the suppressor, after which he was enabled receiver with a random car in between. After 170 seconds, the car with the suppressor was prepar the IAOD at the curb,
and the car with the receiver passed that shows a single spike on the graph. After 240 seconds, the car with the receiver turned around and drove past the suppressor again. This is shown in the form of the second burst through 310 seconds. Once the receiver has passed a parked car with a suppressor, the last moved, and overtook the car with the receiver through 450 seconds.

During this measurement, none of the cars could not be traced or you can accept the signal. To report a violation of synchronism on all satellites can be used for coarse localization of the surge.

The analysis showed that the range of the suppressor is highly dependent on the architecture of the receiver. In each scenario, the surge was a strong influence. After detecting interference was required to mitigate their effect in the receiver. Include measures to mitigate the short-term Fourier transformation or wave packets. Using the IpexSR software interface, you can run and test these algorithms in real life.

The conclusion States the need to take measures against the use of road suppressors. For allegations of use of suppressors need to place the detectors. This measure will also allow you to calculate the number of suppressors. Degradation of GNSS-POS is ment poses a threat to the use of intelligent transport systems,
designed to increase the safety of driving. Therefore, to prevent and mitigate the effect of interference must be the object of studies for system designers highway connections. Interference in GNSS systems need to be tackled in exactly the same way as other dangers on the roads.

The technology selected for the prototype.

The advantage of this technology is that it shows the ability to detect jamming and can lead them count. The disadvantage of this technology is that it does not describe how to conduct the process of object identification according to the presence of suppressors signals. For this technology to identify the car with the hijacker among the General traffic is not possible.

Meanwhile, to catch the hijacker important is the discovery of a stolen car. Very often hijacks the car owner fixes the fact of theft after theft and signals to the police about theft of the car too late, when the hijacker drove all the police offices, and perhaps even moved to another area. That is why it is important to record the process of object identification according to the presence of suppressors signals. If this is done, it will be possible to catch the thieves before the moment when the owner of the car will detect the fact of theft.

The technical result of the claimed invention is increased the e efficiency of detection of stolen vehicles.

This technical result is achieved due to the fact that the detection of stolen vehicles by the presence of suppressors signals, characterized by the use of static control points placed on the highways and containing the receivers to detect the source of the interference of GPS signals, operating on the basis of monitoring the ratio of signal-to-noise suppressor (JNR), characterized in that near the receiver to detect the source of the interference of GPS signals set the receiver to detect the source of the interference of GSM signals, at least one video camera and the wireless node, and detecting interference spend antennas with narrow beam moreover, upon detection of the source of the interference signals of the GPS and/or GSM signals with a corresponding receiver, alarm, which with a number of installed cameras do photo or video of cars on the road; then the received type information of the source of the interference signals and the received image is passed through the node wireless communication to the remote server on which the write data; collected on server data from a variety of static control stations installed in different places of the highway, is processed further by allocating the same type of interference signals, which make the analysis and the views of all cars,
passing static points, followed by determination of the dynamics and direction of hire, under which is the source of interference, their license plate, and further, upon detection of license plates of vehicles which were recorded by security cameras at the moment of detection of the interference, information about the numbers of cars and the dynamics of their motion is transmitted to the posts of road patrol service within the zones from the last place, which was recorded last source of interference.

The implementation of the invention

The claimed method may be implemented, for example, by lining up the next adaptive systems. This allows the system to cater for the existing local area. For this static control point placed in the specified area. Choose ranges to control what type of suppressor signals will be identified and on what bands: GSM 900, DCS 1800, 3G/UMTS 2100, 3G/UMTS 900, CDMA 450, 4G/LTE800, 4G/LTE2500, Wi-Fi and others). The system "remembers" the ratio of the noise/signal (for each range for each value of the carrier frequency).

Next, the system can be configured by the operator manually on the basis of conditions:

what kind of a suppressor signals will identify (what ranges will be monitored);

- what is the threshold alarms (for example, is reviste signal/noise by 10 DB);

- will there be exceeded in the whole range (for example, in the whole range of GSM) or just in some parts of the range;

- compare the excess signal to noise in one range to another (for example, sharply, a large signal level range GSM DownLink 925-960 MHz, our system takes a close range 900-920) if this range is also observed at the same time, sharp is exceeded, it is likely that operates some sort of broadband disturbance, which is not of interest. If not, then most likely jammed precise signals of the GSM and the system is triggered. Similarly for other communication systems. That is, our system is more intelligent - when setting the operator of this mode of our invention is to identify all consecutive suppressors of signals, but only those that operate at frequencies of certain types of communications.

Reference data for estimating the excess signal/noise suppressor can be collected experimentally, why take the car, he placed different types of suppressors of radio signals ("jamming"), then test the car passing under the detectors at speeds of, for example, from 1 to 180 km/hour, and the detectors pick up on different height levels. The system "remembers" the maximum and minimum parameters (signal/W is mA
ranges, compared with close ranges (see above) when driving a car with a "scrambler" that allows the system to identify the more likely a car with a "scrambler" in this particular local area in a particular installation at a certain height. Antenna system with a narrow chart orientation gives a small "spot" under the detection system suppressors radio, if it is located somewhere at the top.

Static control points (1) (see Fig.1, Figs.2) place on the highways (11). The control points (1) contain the receivers to detect the source of the interference of GPS signals (4) and receivers to detect the source of the interference of GSM signals (5), functioning on the basis of monitoring the ratio of signal-to-noise suppressor.

In case of detection of the source of the interference signals of the GPS and/or GSM signals with a corresponding receiver, alarm, which with a number of video cameras (2) make a photo or video hire (13) on the road (11) in the zone (12) possible action "silencers".

The information obtained about the type of the source of the interference signals and the received image received in the microprocessor (7), which Fort the range of the data packet and transmits it using the wireless node (6) via the Internet (8) on the remote server (9),
on which record data.

Collected on the server (9) data from a variety of static control stations installed in various locations on the highway (11), and further processed by allocating the same type of interference signals, which make the analysis of images of all vehicles passing a static items (1), with subsequent determination of the dynamics and movement of vehicles (13), in the group which is the source of interference is possible, and the isolation of the specific vehicle by analyzing data from more than one statistical item.

The selected group of cars (13) determine the number plates. The identification of the vehicle can be performed, for example, through a system of determining the numbers of vehicles "KODOS-Auto" [4].

Then make a comparison of the license plate and if it finds a matching license plates of vehicles which were recorded by security cameras at the moment of detection of the interference, information about these rooms for hire and the dynamics of their motion is transmitted to the posts (10) road patrol services within the zones from the last place, which was recorded last source of interference.

On the posts (10) road patrol produce a stop cars to check the documents of the drivers. In the absence of tehdasmittaus the driver he may be detained until the investigation as a potential hijacker or
if documents are in order, but in the cabin it auto detected "jamming", it can also be detained and fined, because he breaks the law, creating interference in radio systems.
